Bun

bun update

To update all dependencies to the latest version:

bun update

To update a specific dependency to the latest version:

bun update [package]

--interactive

For a more controlled update experience, use the --interactive flag to select which packages to update:

bun update --interactive
bun update -i

This launches an interactive terminal interface that shows all outdated packages with their current and target versions. You can then select which packages to update.

Interactive Interface

The interface displays packages grouped by dependency type:

? Select packages to update - Space to toggle, Enter to confirm, a to select all, n to select none, i to invert, l to toggle latest

  dependencies                Current  Target   Latest
    □ react                   17.0.2   18.2.0   18.3.1
    □ lodash                  4.17.20  4.17.21  4.17.21

  devDependencies             Current  Target   Latest
    □ typescript              4.8.0    5.0.0    5.3.3
    □ @types/node             16.11.7  18.0.0   20.11.5

  optionalDependencies        Current  Target   Latest
    □ some-optional-package   1.0.0    1.1.0    1.2.0

Sections:

  • Packages are grouped under section headers: dependencies, devDependencies, peerDependencies, optionalDependencies
  • Each section shows column headers aligned with the package data

Columns:

  • Package: Package name (may have suffix like dev, peer, optional for clarity)
  • Current: Currently installed version
  • Target: Version that would be installed (respects semver constraints)
  • Latest: Latest available version

Keyboard Controls

Selection:

  • Space: Toggle package selection
  • Enter: Confirm selections and update
  • a/A: Select all packages
  • n/N: Select none
  • i/I: Invert selection

Navigation:

  • ↑/↓ Arrow keys or j/k: Move cursor
  • l/L: Toggle between target and latest version for current package

Exit:

  • Ctrl+C or Ctrl+D: Cancel without updating

Visual Indicators

  • Selected packages (will be updated)
  • Unselected packages
  • > Current cursor position
  • Colors: Red (major), yellow (minor), green (patch) version changes
  • Underlined: Currently selected update target

Package Grouping

Packages are organized in sections by dependency type:

  • dependencies - Regular runtime dependencies
  • devDependencies - Development dependencies
  • peerDependencies - Peer dependencies
  • optionalDependencies - Optional dependencies

Within each section, individual packages may have additional suffixes ( dev, peer, optional) for extra clarity.

--latest

By default, bun update will update to the latest version of a dependency that satisfies the version range specified in your package.json.

To update to the latest version, regardless of if it's compatible with the current version range, use the --latest flag:

bun update --latest

In interactive mode, you can toggle individual packages between their target version (respecting semver) and latest version using the l key.

For example, with the following package.json:

{
  "dependencies": {
    "react": "^17.0.2"
  }
}
  • bun update would update to a version that matches 17.x.
  • bun update --latest would update to a version that matches 18.x or later.
